Abstract
This paper proposes a unified AC chopper topology that can generate both non-inverting and inverting AC voltages. It is therefore suitable for compensating utility voltage sag-swell in domestic consumer and industry infeeds. The proposed converter is able to save on the passive device footprint and improve dynamic performance compared to other similar candidates. The topology derivation, operating principle and performance evaluation are analysed in this paper. Simulation results are presented to assess the proposed scheme with in-phase and out-phase AC voltages generated from a fixed grid input to compensate the voltage sag-swell disturbances in the utility.
